【摘要】 应用AFLP技术,对60个栽培蕉和野生蕉种进行了遗传多样性分析及分类研究。在相似系数0.62的水平上将供试的60份蕉类植物分为4个群体;在相似系数0.64的水平上将栽培蕉划为两个类群;在相似系数0.83的水平上将香牙蕉类群划分为6个亚群;认为传统地将Cavend ish亚群分为5个类别的分类依据与基因型之间并无严格的对应关系。将Saba归入ABB群体;吊罗矮蕉和北大矮蕉2号很可能是同一品种;国家果树种质广州香蕉圃收集的小米蕉、63-1与华农香蕉园种植的小米蕉、63-1均属同名异物情况。更多还原

【Abstract】 AFLP analysis revealed an abundant genetic diversity among banana.The sixty germplasms could be divided into four groups according to the Dice similarity coefficient 0.62.On the higher coefficient level,cultivated banana groups were divided into two subgroups.MusaAAA group xiangyajiao were divided into six subgroups.The traditional classification of Cavendish subgroup based on caudex height was not corresponded with genotypes.The Phillippine Plantain"Saba" was clustered into"ABB"group.Diaoluoaijiao and Beida’ aijiao No.2 were probably the same cultivar(synonyrn).Two homonyms were identificated(Xiaomijiao,63-1,respectively).更多还原
